During the last decades, firms have deployed environmental sustainability practices. While most of these practices incur internally within a firm’s boundaries, collaboration with supply chain partners and sharing of information related to the environmental impact of a firm’s products and processes, namely environmental information, has been identified by many firms as essential in order to achieve their environmental and economic goals. In our research, we focus on a specific type of environmental information, the product-related one. We explore the factors influencing the sharing of product-related information, including the role of environmental collaboration, IT Infrastructure capabilities, supply chain integration capabilities and product-related information availability. A questionnaire-based survey is used targeting European firms in the fast moving consumer goods industry. The testing of the research model and hypotheses is performed using the Structural Equation Modelling (SEM) technique with Partial Least Squares (PLS). The results show that environmental collaboration, supply chain integration capability and product-related environmental information availability have a significant effect on sharing of product-related environmental information. However, IT integration capabilities appear not to be an important influencing factor.
